Text relocations in kernel modules

[Shawn Webb]

Let's all calm down here. No need to make this personal. Let's please try
to keep this conversation professional and respectful to all parties
involved.

Richard, I suggest that if you think the current implementation is less
secure than other implementations, you could write a patch and submit it
upstream. I'm sure that the FreeBSD security team would love any patches
that enhance security. Granted, you might have to present a strong case for
a patch of this nature to be accepted upstream, but I'm sure you will learn
a lot about FreeBSD and others (like me) who maintain modified FreeBSD
codebases would benefit from such a patch. I might be interested to help
you develop this patch if you decide to take it on.

Thanks,

Shawn
